Shadow DPS.

Hi!
I'm just simply wondering about my dps, if it's either too low or sufficient enough.
I spent approx 10 minutes on boss dummy, Halo cleave on additional 3 targets, using shadowfiend on cd etc.
I have reached the haste cap "currently at 8085", and yet if feels as if my damage is way too low.
I ended up on 53 800 dps.
Sorry i cannot provide any logs or anything, but i can give you my armory link.

I'm Draenaei, and my racial wich is 14% doesnt show on armory.
I've also been reading up quite a while today on mmo and there seems to be some bashing about SPriests sinle traget dps on some particular bosses, i guess i'm gonna stop comparing me to those Warlocks
